CERTIFIED ELECTRICAL CONTRACTOR STATEMENT

All electrical Installations that are preliminary to positioning of the equipment at the site prepared
for the equipment shall be performed by licensed electrical contractors. In addition, electrical feeds
into the Power Distribution Unit shall be performed by licensed electrical contractors. Other
connections between pieces of electrical equipment, calibrations and testing shall be performed by
qualified GE GE Healthcare personnel. The products involved (and the accompanying electrical
installations) are highly sophisticated, and special engineering competence is required. In
performing all electrical work on these products, GE will use its own specially trained field
engineers. All of GE’s electrical work on these products will comply with the requirements of the
applicable electrical codes.
The purchaser of GE equipment shall only utilize qualified personnel (i.e., GE’s field engineers,
personnel of third-party service companies with equivalent training, or licensed electricians) to
perform electrical servicing on the equipment.

IMPORTANT...X-RAY PROTECTION
X-ray equipment if not properly used may cause injury. Accordingly, the instructions herein
contained should be thoroughly read and understood by everyone who will use the equipment
before you attempt to place this equipment in operation. The General Electric Company, Healthcare
Group, will be glad to assist and cooperate in placing this equipment in use.
Although this apparatus incorporates a high degree of protection against x-radiation other than the
useful beam, no practical design of equipment can provide complete protection. Nor can any
practical design compel the operator to take adequate precautions to prevent the possibility of any
persons carelessly exposing themselves or others to radiation.
It is important that anyone having anything to do with x-radiation be properly trained and fully
acquainted with the recommendations of the National Council on Radiation Protection and
Measurements as published in NCRP Reports available from NCRP Publications, 7910 Woodmont
Avenue, Room 1016, Bethesda, Maryland 20814, and of the International Commission on
Radiation Protection, and take adequate steps to protect against injury.
The equipment is sold with the understanding that the General Electric Company, Healthcare

Preface Publication Conventions

Standardized conventions for representing information is a uniform way of communicating
information to a reader in a consistent manner. Conventions are used so that the reader can easily
recognize the actions or decisions that must be made. There are a number of character and
paragraph styles used in this publication to accomplish this task. Please become familiar with them
before proceeding forward.
It’s important that you read and understand hazard statements, and not just ignore them.

Section 1.0 Safety & Hazard Information

Proper product safety labeling allows a person to safely use or service a product. The format and
style for safety communications reflected in this publication represents the harmonization of IEC/
ISO 3864 and ANSI Z535 standards.
Within this publication, different paragraph and character styles are used to indicated potential
hazards. Paragraph prefixes, such as hazard, caution, danger and warning, are used to identify
important safety information. Text (Hazard) styles are applied to the paragraph contents that are
applicable to each specific safety statement.

1.1 Hazard Messages

Any action that will, could or potentially cause personal injury will be preceded by the safety alert
symbol and an appropriate signal word. The safety alert symbol is the triangle with an exclamation
mark within it. It’s always used next to the signal word to indicate the severity of the hazard.
Together, they are used to indicate a hazard exists.
Signal words describe the severity of possible human injures that may be encountered. The alert
symbol and signal word are placed immediately before any paragraph they affect. Safety
information includes:
1.) Signal Word - The seriousness level of the hazard.
2.) Symbol or Pictorial - The consequence of interaction with the hazard.
3.) Word Message:
a.) The nature of the hazard (i.e. the type of hazard)
b.) How to avoid the hazard.
The safety alert symbol is not used when an action can only cause equipment damage.

1.2 Text Format of Signal Words

DANGER - INDICATES AN IMMINENTLY HAZARDOUS SITUATION WHICH, IF
NOT AVOIDED, WILL RESULT IN DEATH OR SERIOUS INJURY. THIS SIGNAL
WORD IS LIMITED TO THE MOST EXTREME SITUATIONS.
WARNING - INDICATES A POTENTIALLY HAZARDOUS SITUATION WHICH, IF NOT
AVOIDED, COULD RESULT IN DEATH OR SERIOUS INJURY.
Caution - Indicates a potentially hazardous situation which, if not avoided, may result in
minor or moderate injury. It may also be used to alert against unsafe practices.
NOTICE - Indicates information or a company policy that relates directly or indirectly to the
safety of personnel or protection of property. This signal word is associated directly with a

Preface Page 19

Section 2.0 Publication Conventions

2.1 General Paragraph and Character Styles
Prefixes are used to highlight important non-safety related information. Paragraph prefixes (such
as Purpose, Example, Comment or Note) are used to identify important but non-safety related
information. Text styles are also applied to text within each paragraph modified by the specific
prefix.

EXAMPLES OF PREFIXES USED FOR GENERAL INFORMATION:

Purpose: Introduces and provides meaning as to the information contained within the chapter,
section or subsection (such as used at the beginning this chapter, for example).
Note: Conveys information that should be considered important to the reader.
Example: Used to make the reader aware that the paragraph(s) that follow are examples of information
possibly stated previously.
Comment: Represents “additional” information that may or may not be relevant to your situation.

REVISION 8 DIRECTION 5137436-100
2.3 Computer Screen Output/Input Text Character Styles
Within this publication, mono-spaced character styles (fonts) are used to indicate computer text
that’s either screen input and output. Mono-spaced fonts, such courier, are used to indicated text
direction. When you type at your keyboard, you are generating computer input. Occasionally you
will see the math operator “greater-than” and “less-than” symbols used to indicate the start and
finish of variable output. When reading text generated by the computer, you are reading it as
computer generated output. In addition to direction, characters are italicized (e.g. italics) to indicate
information specific to your system or site.
Example: Fixed This paragraph’s font represents computer generated screen “fixed” output.
Output Its output is fixed from the sense that it does not vary from application
to application. It’s the most commonly used style used to indicate
filenames, paths and text that do not change from system to system. The
character style used is a fixed width such as courier.
Example: This paragraph’s font represents computer screen output that is
Variable Output “variable”. It’s used to represent output that varies from application to
application or system to system. Variable output is sometimes found placed
between greater-than and less-than operators for clarification. For
example: <variable_ouput> or <3.45.120.3>. In both cases, the < and >
operators are not part of the actual input.
Example: Fixed This paragraph’s font represents fixed input. It’s computer input that is
Input typed-in via the keyboard. Typed input that does not vary from application
to application or system to system. Fixed text the user is required to
supply as input. For example: cd /usr/3p
Example: This paragraph’s font represents computer input that can vary from
Variable Input application to application or system to system. With variable text, the
user is required to supply system dependent input or information. Variable
input sometimes is placed between greater-than and less-than operators.
For example: <variable_input>. In these cases, the (<>) operators would
be dropped prior to input. For example: ypcat hosts | grep <3.45.120.3>
would be typed into the computer as:
ypcat hosts | grep 3.45.120.3
without the greater-than and less-than operators.

2.4 Buttons, Switches and Keyboard Inputs (Hard & Soft Keys)
Different character styles are used to indicate actions requiring the reader to press either a hard or
soft button, switch or key. Physical hardware, such as buttons and switches, are called hard keys
because they are hard wired or mechanical in nature. A keyboard or on/off switch would be a hard
key. Software or computer generated buttons are called soft keys because they are software
generated. Software driven menu buttons are an example of such keys. Soft and hard keys are
represented differently in this publication.
Example: Hard A power switch ON/OFF or a keyboard key like ENTER is indicated by applying a character style
Keys that uses both over and under-lined bold text that is bold. This is a hard key.
Example: Soft Whereas the computer MENU button that you would click with your mouse or touch with your hand
Keys uses over and under-lined regular text. This is a soft key.

REVISION 8 DIRECTION 5137436-100

Note: Do not use CB8 to Switch the PDU ON or OFF. CB8 in the system cabinet should not be
used to switch power “ON” and “OFF” to the PDU. If this circuit breaker is used, there is a high
probability it will trip when switched to the “ON” position. A high “in-rush” of current causes this
situation.

7.) Switch CB8 and the power switch to the “ON” position. The power switch handle points to the
“I” Position. See Figure 1-7.

Section 3.0 De-Energizing System

Shut down is controlled by both software and hardware. When a shutdown is initiated, application
and the operating software execution is terminated. While this takes place, signals are sent to the
PDU to shut-off system hardware. Complete shutdown takes approximately 1 minute.
1.) From the application interface, using the mouse, click on the tools icon. This selects the
Service User Interface.

2.) Now click on SHUT DOWN.

3.) Now lock out and tag out the facility power to the system, if you wish to perform service. See
Section 1.2 on page 24.

Section 4.0 Equipment Safety - Electrostatic Discharge (ESD)

A sudden discharge of static electricity from your finger or other conductor can destroy static-
sensitive devices or microcircuitry. Often the spark is neither felt nor heard, but damage occurs. An
electronic device exposed to electrostatic discharge (ESD) might not appear to be affected at all
and can work perfectly throughout a normal cycle. The device can function normally for a while, but
it has been degraded in the internal layers, reducing its life expectancy.
Networks built into many integrated circuits provide some protection, but in many cases, the
discharge contains enough power to alter device parameters or melt silicon junctions.

Chapter 1 - - Safety and Service Page 29

4.1 Generating Static
The following table shows that:
• Different activities generate different amounts of static electricity.
• Static electricity increases as humidity decreases.

Relative Humidity
Event 55% 40% 10%
Walking across carpet 7,500 V 15,000 V 35,000 V
Walking across vinyl floor 3,000 V 5,000 V 12,000 V
Motions of bench worker 400 V 800 V 6,000 V
Removing bubble pack from PCB 7,000 V 20,000 V 26,500 V
Packing PCBs in foam-lined box 5,000 V 11,000 V 21,000 V

Many electronic components are sensitive to ESD. Circuitry design and structure determine the
degree of sensitivity. The following packaging and grounding precautions are necessary to prevent
damage to electric components and accessories.
• Transport products in static-safe containers, such as tubes, bags, or boxes to avoid hand
contact.
• Protect all electrostatic parts and assemblies with conductive or approved containers or
packaging.
• Keep electrostatic sensitive parts in their containers until they arrive at static-free stations.
• Place items on a grounded surface before removing them from their container.
• When handling or touching a sensitive component or assembly, ground yourself by touching
the chassis.
• Avoid contact with pins, leads, or circuitry.
• Place reusable electrostatic-sensitive parts from assemblies in protective packaging or
conductive foam.

4.2 Personal Grounding Methods and Equipment

Use the following equipment to prevent static electricity damage to equipment:
• Wrist straps are flexible straps with a maximum of one-megohm +/- 10% resistance in the
ground cords. To provide a proper ground, wear the strap against bare skin. The ground cord
must be connected and fit snugly into the banana plug connector on the grounding mat or
workstation.
• Heel straps, toe straps, and boot straps can be used at standing workstations and are
compatible with most types of shoes or boots. On conductive floors or dissipative floor mats,
use them on both feet with a maximum of one-megohm +/- 10% resistance between the
operator and ground.

REVISION 8 DIRECTION 5137436-100
4.3 Grounding the Work Area
To prevent static damage of components and parts in the work area:
• Cover the work surface with approved static-dissipative material. Provide a wrist strap
connected to the work surface and properly grounded tools and equipment.
• Use static-dissipative mats, foot straps, or air ionizers to give added protection.
• Handle electrostatic sensitive components, parts, and assemblies by the case or PCB
laminate.
• Handle components only at static-free work areas.
• Turn off power and input signals before inserting and removing connectors or test equipment.
• Use fixtures made of static-safe materials when fixtures must directly contact dissipative
surfaces.
• Keep work area free of non-conductive materials, such as ordinary plastic assembly aids and
Styrofoam.

4.4 Recommended Materials and Equipment

Materials and equipment that are recommended for use in preventing static electricity include:
• Antistatic tape, smocks, aprons, or sleeve protectors
• Conductive bins, foam, tabletop workstations with ground cord of one-megohm +/-10%
resistance, and other assembly or soldering aids.
• Static-dissipative table or floor mats with hard tie to ground
• ESD Field service kits
• Static awareness labels
• Wrist straps and footwear straps providing one-megohm +/-10% resistance

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
2.3 Rail Leveling Procedures (using LASER alignment tool)
Note: The LASER alignment tool is the recommended method to level the stationary rails. If a
LASER tool is not available, alternative methods to level the stationary rails can be found in the
Appendix A - Section 2.0 Rail Leveling Procedures (Water-Level or Transit) on page 248.

1.) Mount both stationary rails in place using all bolts and then tighten bolts.
2.) Determine a convenient location in the room to set up the LASER alignment tool. Set up the
LASER alignment tool tripod and place the LASER alignment tool on the tripod.
3.) Using the LASER leveling screws, level the LASER at 0 degrees and at 90 degrees. The
LASER must be level at both angle positions. Turn the LASER back and forth between 0
degrees and 90 degrees, and adjust until correct level is achieved.
4.) Attach the steel tape measure, supplied with the LASER kit, to the stationary rail at one of the
mounting bolt locations. Refer to Figure 3-3.
5.) Turn the LASER ON and rotate LASER so that the beam hits the tape measure.

6.) Take readings at each mounting bolt location and record these readings. Determine the
lowest bottom point of the stationary rails. This is the reference value. Calculate the difference
between this reference value and the other bolt locations to 1/32” (0.8 mm). Use these
difference calculations to determine height and number of shims required at each bolt hole.
Shims will be required and placed at points with calculated differences greater than 1/32”(0.8
mm).
7.) When all measurements have been recorded, turn the LASER OFF.
8.) Proceed to Section 2.3 (Rail and Shim Installation).

2.4 Rail and Shim Installation

1.) Loosen all bolts until the bolts are finger tight. At each bolt location, place the previously

Page 48 Section 2.0 - Inboard Stationary Rails

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
determined shims between the rail and the ceiling steelwork. Re-tighten all bolts.
2.) Check stationary rail parallelism:
a.) Measure the spacing between the rails. It must be within 1/8” (3.2 mm) of the specified
value. Refer to Figure 3-4. The final distance between the outside edges of the
stationary rails should be 58.36 inches +/- 1/8 in. (1482 mm +/- 3.2 mm) as shown in
Figure 3-5.
b.) Measure the distance from one end of a rail to the same point on the opposite end of the
other rail. These are the rails' diagonals. Compare both measurements. The rails are
parallel if the diagonals are equal.
3.) Re-measure stationary rail levelness at each bolt location. Adjust shims accordingly so
that all mounting bolt readings are equal within 1/32” (0.8 mm).
4.) Retighten all bolts.
5.) Using a two-foot level perpendicular to the rail at each bolt location, insure that each stationary
rail is not twisted. Adjust shims accordingly. Re-tighten bolts.

7.) Turn the lifting fixture cranks equally to raise the bridge up to the stationary rails. Carefully
position the bridge so that the bearings of the rear cross-tie are placed into the rear stationary
rail. Note that two of these bearings are now made of a plastic material and more caution
is required to prevent damage to these bearings.
8.) Place the front cross-tie back into its original position on the bridge, with the bearings inside
the front stationary rail and secure loosely to the bridge rails with the eight screws (apply
Loctite 242 (Blue) to the screw threads) and four plates removed earlier.
If the holes in the bridge rails and cross-tie don’t line up, place a loop of strapping around the
bridge in the area of the front cross-tie. Wind it tight with a screw driver to pull the bridge rails

3.8 Bridge Anti-Backlash Assemblies
Note: The anti-backlash adjustment must be performed before the longitudinal drive belt alignment and
longitudinal drive belt tensioning.

Purpose of Anti-Backlash Assembly: The purpose of applying a specific amount of force (via the
anti-backlash assemblies) is to react against forces produced when the OTS is accelerating in a
longitudinal direction during auto-positioning or tomo sweeps. The force applied by the anti-
backlash assemblies cannot be too high or the bridge bearings may be damaged (the bearings on
the rear of the bridge are very difficult to replace). These plastic bearings were introduced so that
the bearing material does not wear on the aluminum stationary rails like steel bearings would. High
applied force will also increase moving efforts in the longitudinal direction.
1.) Install two anti-backlash assemblies to the top of the bridge rails, behind the rear stationary
rail, using two bolts, washers and lockwashers on each assembly. See Figure 4-37 and
Figure 4-38.

Figure 4-37 Anti-Backlash Assembly Locations

Page 74 Section 3.0 - Bridge and Carriage

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100

Figure 4-38 Anti-Backlash Assembly

2.) On each anti-backlash assembly, adjust the tensioning bolt clockwise until the bearing just
touches the rear surface of the stationary rail (finger tight).
3.) Place a mark on the tensioning bolts so that adjustment revolutions of the bolts can be
counted.
4.) Turn the tensioning bolts 5 turns clockwise or until the bolts reach the end of travel. Over-
tightening of the tensioning bolts draws the bridge internal bearings tight to the rear suface of
the stationary rails.
5.) Run the bridge back and forth 1 - 2 meters (3 - 6 feet) several times to finish drawing the bridge
up to the rear stationary rail.
6.) Turn both of the tensioning bolts counterclockwise until the bearings no long touch the rear
surface of the stationary rail. Do not move the bridge until the adjustments in steps 7 and 8
are completed.
7.) On each anti-backlash assembly, adjust the tensioning bolt clockwise until the bearing just
touches the rear surface of the stationary rail (finger tight).
8.) On each anti-backlash assembly, adjust the tensioning bolt an additional 3 turns clockwise.
This produces the proper spring force of 50 lb-f or 225N. Make sure each bolt has equal turns
so that the bridge is perpendicular to the stationary rails. Unequal force could result in the
bridge being at an angle.
9.) Apply Loctite 242 (Blue) to the mounting screws and install the anti-backlash assembly
covers. See Figure 4-39.

4.1 Longitudinal Belt Installation and Tracking
1.) Route the belt through longitudinal drive assembly; over the top idler, under the drive pulley
and back out over the top other idler. See Figure 4-40.

Figure 4-40 Longitudinal Drive Belt Installation

2.) Verify that the longitudinal drive assembly is installed flush against the rail.
a.) There should be no gap between the longitudinal drive and the bridge rail surface. See
Figure 4-41.

Figure 4-41 Bad and Good Longitudinal Drive Alignment

b.) If a gap exists, loosen the screws and push the longitudinal drive flush against the rail.
While holding the drive in position, tighten the fasteners.
3.) Attach the belt.

Chapter 4 - Overhead Tube Support (OTS) Page 77

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
a.) At the anchor (foot) end of the longitudinal rail, install the belt. See Figure 4-42.

Note: Tension Line - Use a Mono-Filament “Fishing” Line (8 pound test, 0.25 mm) or equivalent to
measure belt deflection. “It's important that the line you choose have a small mass. A high
mass causes the line to sag in the middle and your resulting tension will be wrong.”

i.) Place one end of the tensioning line into the anchor end belt clamp and position it
towards the middle on the tooth side of the belt. “We want the belt clamp to capture
both the belt and the line when the clamp is secured.”
ii.) Now place the belt between the clamp and the plate along with the tension line. “The
clamp must capture seven (minimum) teeth on the belt when properly installed.”
iii.) With the belt and tensioning line in the belt clamp, torque the belt clamp (M6 Hex
Socket) screws to 9.9 Nm (7.3 lbs-ft).

Figure 4-42 Anchor plate assembly (Foot End)

iv.) Tighten the two (M10 Hex Socket) plate screws that secure the anchor plate to the
rail.
v.) Loosen each of the plate screws that secure the anchor plate by one turn
counterclockwise. “We want the tension plate to be slightly loose so it can move
during our tracking adjustment.”
b.) At the tensioning (head) end of the longitudinal rail, install the belt. See Figure 4-43.
i.) Remove the four (M6 Hex Socket) belt clamp screws.

Figure 4-43 Tensioning Clamp

ii.) Create belt tension adjustment range; turn the tension adjustment screw
counterclockwise until the belt clamp slightly overhangs the plate by ½ of a tooth. “We
want the tensioning belt clamp as far out as possible, so you have the most tension
range. As you turn the adjustment screw, the belt clamp plate will move in (clockwise)

Page 78 Section 4.0 - Longitudinal and Lateral Drive Belt Assemblies

or out (counterclockwise).” See Figure 4-44.

Figure 4-44 Tensioning Belt Clamp Setup

iii.) Pull out the slack in the belt and position it parallel to the belt clamp. "We want the
belt pulled tight so that it is captured by seven teeth of the belt clamp."
iv.) Make marks (using a marker) on the belt so that it can be placed in the same position
after you cut the belt to length. See Figure 4-45.

Figure 4-45 Marking Belt Position in Clamp

a.) Place a mark on the belt where it will be cut off and still be captured by seven
clamp teeth. “The belt clamp must capture seven teeth of the belt after you cut off
the excess length.”
b.) Place a mark on the belt where it enters the belt clamp. “This mark serves as
additional reference point. It helps to ensure that you will capture the proper
amount of belt teeth in the clamp. The mark should be visible when the clamp is
secured.”

Chapter 4 - Overhead Tube Support (OTS) Page 79

v.) Cut the belt off at the "cut-off" mark you’ve made. See Figure 4-46.

Figure 4-46 Belt Markings

vi.) Place the cut-off end of the belt into the tensioner belt clamp and secure the belt
clamp screws by turning them clockwise. “Use the marks you made on the belt to
position the belt.” See Figure 4-47.

vii.) Tighten the two (M10 Hex Socket) screws that secure the tensioner plate to the rail.
See Figure 4-48.

adjustment."
4.) Align the tracking of the belt with respect to the rails. See Figure 4-49.
a.) Center the belt on the longitudinal drive pulley.
i.) Move the bridge back and forth between the head and foot ends of the stationary rails
several times. “We want the tension plate and anchor plate to align themselves to the
rails.”
ii.) Move the bridge around the stationary rails midpoint until you can find a position
where the belt tracks down the center of the longitudinal drive pulley. The belt is
centered when there is an equal gap between the belt edges and drive pulley flanges
on both sides.
b.) Measure the distance from the stationary rail to the nearest belt edge at the longitudinal
drive idler pulley and set the belt position at the head and foot ends of the rail equally.
i.) At the longitudinal drive assembly: measure and record the "tracking distance" from
the edge of the stationary rail to the nearest belt edge at the idler pulley. See
Figure 4-49.

Figure 4-49 Belt Tracking at the Longitudinal Drive

ii.) At the head end of the stationary rail: position the edge of the belt with respect to the
stationary rail at the same distance you recorded at the longitudinal drive assembly.
iii.) At the foot end of the stationary rail: position the edge of the belt with respect to the
stationary rail at the same distance you recorded at the longitudinal drive assembly.
iv.) Move the bridge back and forth between the head and foot end several times. "We
want the belt plates to align themselves again to the rail following adjustment."
v.) Measure the distance from the rail to the edge of the belt at both ends again and verify
adjustment.
c.) Secure the plates, if your measurements are equal or within specification.
i.) If the variance between the belt and rail on both ends is less than or equal to +/-
0.5 mm, then secure the plate screws on the anchor (foot) and tensioning (head)
ends of the rail.
• At the foot end, hold the anchor plate so the plate doesn’t move, while you
torque the (M10 Hex Socket) screws to 48 Nm (35.4 lbs-ft). The plate will
want to move when you tighten it because of the turning of the screw and

Chapter 4 - Overhead Tube Support (OTS) Page 81

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
washer.
• At the head end, hold the tension plate so the plate doesn’t move, while you
torque the (M10 Hex Socket) screws to 48 Nm (35.4 lbs-ft). "The plate will
want to move when you tighten it because of the turning of the screw and
washer."
ii.) If the variance between the belt and rail on either end exceeds 1 mm, repeat steps
b.) and c.) above.
d.) Finally, verify that the belt does not rub "excessively" against the metal flange of
the drive pulley at any point along its entire longitudinal travel.
“It is normal for the belt to move (walk) a little from side to side on the drive pulley. It is not
normal to have excessive contact with the drive pulley flange, which can later result in
“squeaking” noises as the bridge is moved longitudinally.”
* If the belt occasionally touches the metal flange on the drive pulley – tracking is good.
* If the belt constantly touches the metal flanges or drives hard into the drive pulley
metal flange or makes any noise during tracking – tracking is bad and should be
adjusted.
5.) Set the belt tension.

a.) Move the bridge longitudinally until it is two meters from the anchor end belt clamp, as
measured from a tangent point on top of the idler pulley to the point where the tension line
exits the anchor end belt clamp. See Figure 4-50.

Figure 4-50 Belt Tension Setup

b.) Using clamping devices (i.e. locking pliers, C-clamps, etc.), secure the bridge to the
stationary rail to prevent it from moving.
c.) Set up the tension line.
i.) Loop the tension line over the idler and down the middle of the belt.
ii.) While maintaining this position, pull the line tight. The line should make a well-defined
sound (pitch) if pulled and released.
iii.) Secure the line to prevent loss of tension.
iv.) Place a mark on the belt that is one meter from where the tension line exits the anchor
end belt clamp.

Page 82 Section 4.0 - Longitudinal and Lateral Drive Belt Assemblies

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
v.) Using a ruler, measure the distance from the tension line to the belt teeth immediately
above the 1-meter marking.
vi.) The distance (d) between the tension line and the belt at this point should be 6
millimeters (+/- 1 millimeter). Set the tension at the tensioner (head) end of the
stationary rail to achieve this.
a.) Turn the tension screw (located on the head end tension assembly) until 5 or 6
millimeters of deflection is achieved.
• Clockwise to increase tension.
• Counterclockwise to decrease tension.
b.) Torque the belt clamp (M6 Hex Socket) screws to 9.9 Nm (7.3 lbs-ft) each.
vii.) Remove any clamps used to hold the bridge stationary.
viii.)Do not remove the tension line from the anchor clamp. Store the excess line and
secure it to the top of the rail out of sight for future use.
6.) Install tensioner assembly cover plate.
a.) Apply a small amount of non-permanent thread locker, such as Loctite 242 (Blue), to
screw (M6 Hex Socket) threads.
b.) Torque screws 9.9 Nm (7.3 lbs-ft).

6.2 Fill Table Chiller with Coolant
Note: This section is to be performed by the local field engineer.

Always use a funnel when adding coolant to the chiller. The coolant provided for filling the chiller is
water protected by a fungicide. In its undiluted form this fungicide is toxic, but in the solution
provided it is very dilute and is not dangerous to health when handled correctly. However, when
handling the solution you should treat it with care and avoid unnecessary contact (wear goggles).
Waste solution in the concentration used will not cause pollution if disposed in a non-sensitive
environment. See below for First Aid advice.

Note: 1.) In case of contact with chiller coolant:

- Immediately flush eyes or skin with plenty of water for at least 15 minutes.
- In case of eye contact, call a physician immediately.
- If swallowed, drink one to two glasses of water or milk. Avoid alcohol. Call a physician
immediately.
- Remove and wash contaminated clothing before reuse.
2.) When filling or topping up the unit, take great care to keep water away from the vents, the ON/
OFF switch and the power connection. Do not immerse the unit in any liquid.
3.) The fungicide used in the coolant is toxic. Dispose of old surplus coolant with care.

1.) Remove the reservoir cap located on the top of the detector chiller.
2.) Place paper towels on chiller to prevent coolant spills from entering chiller.
3.) Using a funnel, pour coolant liquid into the reservoir until the coolant level is about 1” (2.5 cm)
from the top of the reservoir.
4.) After system powerup, run the chiller for 5 minutes then recheck the level and add additional
coolant if necessary.
5.) Reinstall the cap on the reservoir and tighten it securely.

1.) From room layout drawings, locate wall stand mounting location.

Potential for Potential for Injury if Equipment is not fastened properly: Anchors must be a minimum
Injury. of 150mm from any concrete edge including ducts and cracks. In addition, the general
condition of the concrete in the immediate mounting area should be inspected to
ensure that anchors will be set in good quality concrete.

2.) Move wall stand into position and slowly lower wall stand until baseplate contacts the floor and
the front leveling bolt is directly over the intersection of the lines locating the first hole and rear
leveling bolt is bisected by the longitudinal location line. (Leveling bolts must not extend
beyond the bottom of baseplate.) The support arm can be used for added leverage. See
Figure 6-17.

Figure 6-17 SUPPORT ARM USED FOR POSITIONING

3.) Turn wall stand leveling bolts until they contact the mounting sub-plate.
4.) Remove the 4 caster assemblies from the baseplate.
5.) Completely loosen (but do not remove) the 3 nuts that secure the sub-plate to the baseplate.
See Figure 6-18. This will allow the sub-plate to float away from the baseplate during leveling.

6.) Attach the supplied plumb line by screwing the bushing into the hole in the bottom of the
horizontal arm. The plumb bob should rest just above the top of the baseplate. See Figure 6-
19, Figure 6-21 and Figure 6-23. Adjust the plumb bob height by tying a knot in the line or
taping it to the carriage.

Figure 6-19 PLUMB LINE ATTACHMENT

Note: If a leveling bolt is turned to raise one side of the stand, the two leveling bolts which affect the
other plane must be adjusted equally until they touch the sub-plate, since they will have been
raised off the sub-plate. Like wise, if the leveling bolt is turned to lower one side of the stand,
the two leveling bolts which affect the other plane must be adjusted upward because the stand
will be pivoting on them.
7.) Remove the support arm by removing the two brackets that mount the support arm to the
vertical column of both stands.
If desired, put the four mounting bolts back in the vertical column. However, be sure to
verify that the bolts do not interfere with the counterweight vertical motion. See

Section 12.0 Final OTS/Tube/WS Alignment

The following procedures must be done before performing positioner calibration of the wall stand.

Note: This chapter is to be performed by the local field engineer.

12.1 X-ray Beam to SID Travel Alignment

The X-ray beam must be parallel to the axis used to vary the wall stand SID to assure proper
alignment at all SIDs.
1.) Set the the keyswitch on the rear of the UIF to ’override’ position (yellow and green LEDs flash
on the left side of the UIF).
2.) Rotate the X-ray tube and the OTS column until the collimator faces the wall stand. It is
important to position the X-ray tube and column in the same manner as it will be used at the
site.
3.) Using a level, verify that the patient barrier is in the vertical position (0 degrees). See Figure 6-
48.

Figure 6-48 Patient Barrier Vertical (0 degrees) and Horizontal (90 degrees)

4.) Using a level, verify that the rails of the collimator are vertical.
5.) Position the OTS for a SID of 100 cm (if using tape measure, set to 95 cm).
6.) With the collimator crosshair shining on the center of the patient barrier (at 0 degree position),,
move the OTS to vary the SID while preventing the OTS from moving horizontally (left to right)
across the barrier.
7.) Verify that the collimator crosshair does not shift more than 3 mm horizontally as the SID is
varied from 100 cm to 180 cm (if using tape measure, vary from 95 cm to 175 cm).
8.) If adjustment is necessary, perform the OTS Column Rotation calibration. If the alignment is
still off, recheck Wall Stand to Stationary Rail alignment in Section 10.0 Initial Mechanical
Alignment on page 142.
9.) Position the OTS for a SID of 100 cm (if using tape measure, set to 95 cm).
10.) With the laser line shining on the center of the patient barrier (at 90 degree position),, move

Page 144 Section 12.0 - Final OTS/Tube/WS Alignment

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
the OTS to vary the SID while preventing the OTS from moving vertically (up or down) across
the barrier.
11.) Verify that the laser line does not shift more than 3 mm vertically as the SID is varied from 100
cm to 180 cm (if using tape measure, vary from 95 cm to 175 cm).
12.) If adjustment is necessary, perform the X-ray Tube Angulation calibration. Another possible
cause of excess vertical shift can be improperly leveled stationary rails.

12.2 Detector Perpendicular to X-ray Beam Adjustment

1.) Move the wall stand detector until it is approximately in the middle of its vertical travel.
2.) Rotate the collimator until the laser light projects a vertical line on the wall stand.
3.) Attach a mirror to the face of the patient barrier. See Figure 6-49.

Figure 6-49 Mirror on Detector Patient Barrier

4.) Turn on the laser and position the OTS so the laser line hits the mirror.

Potential for damage to eyesight. Do not look directly into source or reflected laser beam.

5.) Observe the reflected laser beam line at the collimator. Use a piece of paper to see the line.
See Figure 6-50.

Chapter 6 - Wall Stand & Extended Wall Stand Page 145

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100

Figure 6-50 Reflected Line Within Limits

6.) Rotate the wall stand until the reflected line is within the edges of the opening of the laser
source. This assures that the detector is perpendicular to the X-ray beam.
7.) Move the OTS to vary the SID from 100 cm to 180 cm. The reflected line must stay within the
edges of the opening of the laser source.
8.) Remove mirror from wall stand.

12.3 Vertical Tracking Adjustment

1.) Set the the keyswitch on the rear of the UIF to ’normal’ position (yellow and green LEDs no
longer flashing on the left side of the UIF).
1.) Position the OTS for a SID of 180 cm.
2.) Lower the detector to its minimum height and vertically position the OTS to maintain alignment.
3.) Center the laser light on the patient barrier.
4.) Raise the detector to its maximum height and vertically position the OTS to maintain alignment.
5.) Note the location of the laser light on the patient barrier.
6.) If the light shifts laterally (left to right) as the vertical height is varied, it will be necessary to
adjust the lateral tilt of the wall stand so that it tracks the offset of the OTS as the vertical
position of the OTS is varied. When adjusting the lateral tilt of the wall stand, do not allow the
front-to-rear tilt of the wall stand to change from vertical.

Section 3.0 Fill DSA Chiller with Coolant

Note: This section is to be performed by the local field engineer.

Always use a funnel when adding coolant to the chiller. The coolant provided for filling the chiller is
water protected by a fungicide. In its undiluted form this fungicide is toxic, but in the solution
provided it is very dilute and is not dangerous to health when handled correctly. However, when
handling the solution you should treat it with care and avoid unnecessary contact (wear goggles).
Waste solution in the concentration used will not cause pollution if disposed in a non-sensitive
environment. See below for First Aid advice.

Note: • First Aid in case of contact with chiller coolant:

- Immediately flush eyes or skin with plenty of water for at least 15 minutes.
- In case of eye contact, call a physician immediately.
- If swallowed, drink one to two glasses of water or milk. Avoid alcohol. Call a physician
immediately.
- Remove and wash contaminated clothing before reuse.
• When filling or topping up the unit, take great care to keep water away from the vents, the ON/
OFF switch and the power connection. Do not immerse the unit in any liquid.
• The fungicide used in the coolant is toxic. Dispose of old surplus coolant with care.

1.) Remove the reservoir cap located on the top of the detector chiller. See Figure 7-4.

Figure 7-4 REMOVE CHILLER CAP

2.) Using a funnel, pour coolant liquid into the reservoir until the coolant level is about 1” (2.5 cm)
from the top of the reservoir. See Figure 7-5.

Figure 7-5 FILL CHILLER WITH COOLANT

3.) After system powerup, run the chiller for 5 minutes then recheck the level and add additional
coolant if necessary.
4.) Reinstall the cap on the reservoir and tighten it securely.

Section 1.0 Summary Checklist

Pull all MIS cables between sub-systems

Connect MIS cables to (installed) sub-systems

Section 2.0 Routing

• System MIS cables should be pulled to/from the System Cabinet before the System Cabinet
is moved into the final mounting position.
• Some system cables are pre-connected to a sub-system and should not be disconnected in
order to pull the cable(s) through the conduits or wall ducts. Therefore, the following cables
should be pulled in the directions listed below:
- Cables between the Wall Stand and the System Cabinet should be pulled from the Wall
Stand to the System Cabinet.
- Cables between the Table and the System Cabinet should be pulled from the Table to
the System Cabinet.
- Cables between the Wall Stand and the Magic PC should be pulled from the Wall Stand
(through the System Cabinet) to the Magic PC.
• If excess cables must be coiled and stored, they must be coiled in a “figure 8" configuration,
NOT a single coil stack.
• Power cables must be kept separate from signal cables as much as possible. In wall ducts or
raceway, power cables should be routed in a separate channel from signal cables. Inside the
System Cabinet, power cables should not be bundled together with signal cables.

Section 3.0 System Cables

Note: Refer to the following document for details on system cabling: 5137438-100, Definium 8000 -
System Schematics and Drawings (this document contains the MIS Map).

Standard Service Tools

Parts:
• Wall mounting bracket (supplied with cabinet).
• Customer or contractor supplied wall and floor anchoring devices that meet local requirements
(seismic, etc.).
• Customer or contractor supplied wiring/cable conduits, fittings, etc.

Initial Conditions:
Before installation work begins, the site should be checked to verify the correctness of junction
box sizes, their locations, the number and sizes of interconnecting wiring and proper power
availability in the room. In addition, cabinet mounting methods should already be determined
prior to cabinet installation (customer supplied attaching devices). Refer to Direction 5137435-
100, Definium 8000 Pre-Installation.

Procedure:
1.) Unbolt the wall mount bracket from the top of the System Cabinet. If the cabinet will be
mounted flush to the wall, then the wall mount bracket should be bolted flush to the rear of the
cabinet as shown in Figure 10-1. If the cabinet cannot be mounted flush to the wall due to an
obstruction (such as wall-mounted duct-work or raceway), then the wall mount bracket should
be bolted to the cabinet in the extended position by using the other set of mounting holes.
2.) The System Cabinet will be shipped attached to shipping dollies. Position the cabinet (while
on the dollies) according to your room plan.
3.) Route the system cabinet MIS cables through the cable access opening (rear, bottom or side)
of the cabinet. Lower the cabinet until contact is made with the floor.

c.) Bring the barrier back over the receptor brackets and engage the barrier pins.
d.) Measure the distance between the barrier and the wall stand on both sides. Align the
barrier so that both measurements are equal.
e.) Rotate the receptor 60 degrees and mark the locations for three new 6 mm holes.
f.) Drill three new holes and mount the receptor bracket into place.
13.) There are 3 leveling set screws on each receptor bracket. You will only level the receptor
brackets if the floor is so severely out of level that the barrier pins cannot be inserted into the
receptor brackets.
14.) Once the receptor brackets are secured, the barrier may be rolled into position and the pins
locked into the receptor brackets. Press on both of the side foot pedals to lock the barrier into
place.
15.) Install the image pasting barrier measurement labels as follows:

Note: • The labels give a measurement of the distance between the center of the patient and the mylar
surface. As such, the labels should be attached so that the lower numbers are closer to the
mylar surface.
• Before placing the labels, clean the sides of the lateral arm bars and the recessed area in the
footstand with Windex, Formula 409, or soap and water. Dry thoroughly.

a.) Install the footstand labels:

* The footstand labels are the wider labels.
* Based on the customer’s preference, select the metric or english measurement
labels.
* Place the labels in the recessed areas on the footstand with the lower numbered
ends closest to the mylar surface. See Figure 13-4.

1.) Position radiation probe as shown in Figure 15-1, "Good Geometry".

Figure 15-1 Half Value Layer Probe Positioning - "Good Geometry"

2.) The optimum position for the standard absorber is midway between the focal spot and the
radiation probe. Other positions will introduce reading errors. For example, if the absorber is
placed close to the probe, then the probe will receive excess scatter and the absorber will
appear to have absorbed less.
3.) Set technic factors as follows:
- 80 kVp, 50 to 100 mA, 1/2 to 1 second
- mA and time should be adjusted so that the reading in step 6 contains three significant
digits.
4.) Remove or dial out all filters that are removable by the operator and collimate slightly larger
than the active volume of the probe using the light field.
5.) Make an exposure and measure exposure with no added filters. Record the reading. This
represents 100% transmission level.

2.4 Upper Front and Rear Cover Installation

Note: If above grade floor mounted cable trough is being used, it is possible that the upper covers
could contact the cable trough when the table is driven to its lowest possible height. To avoid
any contact, the lower limit and position switches must be re-adjusted. Refer to Direction
5137439-100, Definium 8000 Renewal Parts and Disassembly/Reassembly, to identify the
lower safety and limit switches. This will mean that the table can not be driven to the lower
specification height and the customer should be notified of this change.

1.) Install the upper front and rear covers with one screw in each upper corner. The screws do not
need to be tightened since the mid-covers will also use these screws to hold them in place.
See Figure 16-8.
Note: The upper front cover has one long recess cut out to allow the front detector assembly bearing
to roll on the bearing strip. The upper rear cover has three small recesses cut out to allow for
the detector bearing rod supports.

Note: The front mid cover has a long cut out and the rear mid cover is solid.
1.) Position the mid covers as shown in Figure 16-10. The detector assembly needs to be raised
to allow the detector handle to fit through the opening in the front mid cover.
Note: The table top must be moved to access these screws when the mid cover is on.
2.) Secure mid covers with the same screws that were used to hold the upper front and rear
covers. Figure 16-10.
Verify that the top of the detector handle does not rub on the opening in the mid-cover. If
necessary, shim the cover to prevent rubbing.

3.1 Final Counterpoise Adjustment
1.) Shut down the system, then turn off system power.
2.) Position the vertical column so that it is in the middle of the vertical range of travel.
3.) If the vertical column tends to drift upward or downward when released, adjust the
counterpoise tensioning bolt to eliminate drift (clockwise rotation results in more lift). See
Figure 16-15. Throughout the range of vertical column travel, the tube/collimator shoud
not drift downward.

Figure 16-15 OTS Counterpoise Tensioning Bolt

4.) Move the vertical column through the complete range of vertical travel. Check for drift at the
top and bottom limits of travel and adjust the counterpoise tensioning bolt to equalize the
amount of drift.

3.2 Install OTS Trim Covers
1.) Install the carriage shipping bolt through the bridge rail and into the carriage to prevent the
OTS carriage from moving during installation of the covers. See Figure 16-16.

Figure 16-16 OTS Carriage Shipping Bolt

Note: Refer to Figure 16-17 for OTS trim cover component identification and locations.

2.) Attach the cover pin receivers to the the sides of the OTS casting. The wider pin receiver is
mounted to the left side (head-end) of the casting. The smaller pin receiver is mounted on the
right side (foot-end) of the casting as shown in Figure 16-17.

Note: When installing or adjusting the brackets on the OTS front and rear covers, place the covers on the
plastic shipping bags to prevent any cosmetic damage to the covers.

3.) Attach the front mounting brackets to the left and right sides of the front cover. Leave the front
mounting bracket screws slightly loose so that they can be adjusted when the cover is
installed.
4.) Attach the baffle covers to the largest OTS column. Slide the baffle up until it touches the
bottom of the cable bracket at the rear of the column, then tighten the four screws.
5.) Position the ladder in front of the OTS. Lift the front cover into position. Rest the left front
mounting bracket on the TSL (Tube Support Logic) assembly. Rest the right front mounting
bracket on the cable drape bundle. It may be necessary to rotate the left and right front
mounting brackets to obtain clearance between the cover and the TSL and/or cable drape
bundle.
6.) When the front cover is properly positioned, attach the front cover brackets to the OTS casting
with four screws and washers. Do not completely tighten the screws; just get them started in
the threaded holes. The bottom of the front cover should be underneath the baffle.
7.) On the left side (head-end), slide the front cover pin into the cover pin receiver. Repeat on the
right side (foot-end). The cover can be flexed in order to slide the pins into the receivers.
8.) Tighten the four front mounting bracket screws to the OTS casting and tighten the two screws
that attach the front mounting brackets to the OTS front cover.
9.) Position the ladder at the rear of the OTS. Lift the rear cover into position and slide the rear
cover pins into the cover pin receivers. Attach the rear cover bracket to the OTS casting with
two screws. If the mounting bracket holes do not line up with the threaded holes in the casting,
the rear mounting bracket can be loosened from the cover adjusted as necessary. The bottom
of the rear cover should be underneath the baffle and the front of the rear cover should engage
with the lip at the rear of the front cover.

2.1 Using a Water-Level Kit
1.) Slide open the battery door on the back of the unit and connect a 9 volt alkaline battery.
Use an alkaline battery only. The use of a non-alkaline or heavy-duty battery will cause unit to
malfunction.
2.) Attach a 30’ (9.14 m) clear plastic 3/8” (9.5 mm) I.D. tube to the connector on the bottom of the
water-level case.
To meet any room installation requirement, greater than 30’ (9.14 m) of tubing can be used
with the water-level unit. The greater the distance from the water-level case (i.e., longer
lengths of tube), the more time that must be allowed for the water line to damp (i.e. reach
equilibrium).
3.) Prepare 3 cups of water solution containing 1/8 teaspoon of salt and enough food color to
enable the water level to be seen more easily.
4.) Remove the plug from the short tube on the water-level case side.
5.) Fill the long plastic tube with water solution. Refer to Figure 17-8.
a.) Place the free end of the long plastic tube in the water solution container and elevate the
container.
b.) Place the water-level case below the level of the water solution container.
c.) Siphon water solution into the long plastic tube by sucking on the short tube on the water-
level case side.
d.) Fill the long plastic tube until the water solution level is slightly below the water-level case.
6.) Insert plugs into both the short and long free tube ends to prevent loss of water.

7.) Mount both stationary rails in place using all bolts and then tighten the bolts. There must be a
minimum of 2" (5.1 cm) between the ends of the stationary rails and the wall.
8.) Tape a six (6) foot or a two (2) meter flexible steel scale to a support rod to stiffen the scale or
tape the zero scale end of a six (6) foot or a two (2) meter flexible steel scale to a stationary
rail. Refer to Figure 17-9.

9.) If using the steel scale with a support rod, hold the tape scale and rod assembly up against the
bottom of the stationary rail surface.
10.) Mount the water-level case in an upright position with the reference line on the side of the case
at some convenient position above the lower end of the tape scale. To insure that the
instrument remains plumb, secure the top and both sides of the water-level case in position.
Refer to Figure 17-10.

11.) Lay out the plastic tube and remove any knots or kinks. Check to make sure that there are no
air bubbles in the tube. Air bubbles will cause inaccurate readings.
To remove air bubbles, remove the plugs from the long tube free end and from the short tube
end on the instrument case. Hold the long tube below the water-level case (at about a 45
degree angle), until a small amount of water flows from the long free tube end. All bubbles
should be gone.

12.) With both plugs removed, bring the free end of the long tube alongside the same tube at the
mounted water-level case. Refer to Figure 17-11. Verify that the water line in the long plastic
tube settles at an equal level at both tubes ends. If the level is not equal, check for air bubbles
in the tube and remove.

13.) To measure the number of shims required, hold the tape scale and rod assembly or tape the
flexible scale up against the stationary rail bottom at each bolt location.
14.) Turn ON the water-level switch.
15.) With both plugs still removed, slowly raise the long tube free end along with the scale and rod
assembly up against the ceiling steelwork at any mounting location. Adjust the water line (up
or down) at the long tube free end until the buzzer first sounds. Refer to Figure 17-12.

16.) Take readings at each mounting bolt location and record these readings. This allows you to
determine the lowest bottom point of the stationary rails. This is the reference value. Calculate
the difference between this reference value and the other bolt locations greater than 1/32” (0.8
mm). Use these difference calculations to determine height and number of shims required at
each bolt hole location.
Shims will be required and placed at all points with a calculated difference of greater than 1/
32” (0.8 mm).
17.) When all measurements have been recorded, turn OFF the water-level switch and replace the
plugs at both the long tube free end and at the short tube on the water-level case side.

18.) Proceed to Section 2.3 (Rail and Shim Installation).

2.2 Using a Transit (Alternate Method)

1.) Mount both stationary rails in place using all bolts and then tighten bolts.
2.) Set up a transit (builder's level) in the center of the area encompassed by the rails. Refer to
Figure 17-13.
Level the transit according to the instructions supplied with the instrument.
3.) Tape a six (6) foot or a two (2) meter flexible steel scale to a support rod to stiffen the scale or
tape the zero scale end of a six (6) foot or a two (2) meter flexible steel scale to a stationary
rail. Refer to Figure 17-9.
4.) To measure the number of shims required, move the scale and hold up to (or tape to) the
stationary rail at each bolt location. Refer to Figure 17-13.
5.) View the scale through the transit. Recheck transit level at each bolt location and re-level if
necessary.
6.) Take readings at each mounting bolt location and record these readings. This allows you to
determine the lowest bottom point of the stationary rails. This is the reference value. Calculate
the difference between this reference value and the other bolt locations greater than 1/32” (0.8
mm). Use these difference calculations to determine height and number of shims required at
each bolt hole location.
Shims will be required and placed at all points with calculated differences greater than 1/32”
(0.8 mm).
7.) Proceed to Section 2.3 (Rail and Shim Installation).

Section 3.0 Modifying the Bridge Length

Note: Modifying bridge length is NOT recommended by GEHC Engineering.
If modification of the bridge is required, YOU MUST CHECK WITH YOUR INSTALLATION
SPECIALIST. Confirm that the length you desire will not limit your ability to purchase future
product options or upgrades (i.e. VolumeRAD).

Page 252 Section 3.0 - Modifying the Bridge Length

GE HEALTHCARE DEFINIUM 8000 INSTALLATION MANUAL
REVISION 8 DIRECTION 5137436-100
If necessary, the OTS bridge may be cut off on either/or both ends using the following procedure:
1.) Remove end cap.
2.) Pry hardened wear strip loose, score with file, and break off 3" shorter than rails are to be cut.
Do not confuse this procedure with the procedure for modifying the stationary rails.
3.) Cut rails square and of equal length.
4.) Chamfer end of rails so that end cap will fit.
5.) Re-bond wear strip.
6.) Place end cap on rails and use as template to drill (3) new holes in each rail.
7.) Replace end cap and mount with original hardware.
